The NM_000314.8(PTEN):c.388_390delCGAinsGGG (p.Arg130Gly) variant causes a missense change. Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 9.52). No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. A different missense at the same amino acid position has been reported as Pathogenic/Likely Pathogenic in ClinVar: p.R130L: Pathogenic/Likely_pathogenic (ClinVar VariationId 376509, 2 stars) Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R130?: Uncertain_significance (ClinVar VariationId 2687576, 0 stars); p.R130?: Uncertain_significance (ClinVar VariationId 2687578, 0 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 1735874, 2 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 3903832, 2 stars); p.R130= (synonymous): Likely_benign (ClinVar VariationId 1648484, 1 star) The same amino acid change has been reported as oncogenic or likely oncogenic in a clinical somatic variant database. The variant position is a cancer hotspot (cancerhotspots.org): 239 samples carry this exact amino acid change out of 1912 samples with a variant at this residue. This exact variant is curated in the UniProt human variants database as Uncertain Significance.

Genes affected

PTEN (HGNC:9588): (phosphatase and tensin homolog) This gene was identified as a tumor suppressor that is mutated in a large number of cancers at high frequency. The protein encoded by this gene is a phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase. It contains a tensin like domain as well as a catalytic domain similar to that of the dual specificity protein tyrosine phosphatases. Unlike most of the protein tyrosine phosphatases, this protein preferentially dephosphorylates phosphoinositide substrates. It negatively regulates intracellular levels of phosphatidylinositol-3,4,5-trisphosphate in cells and functions as a tumor suppressor by negatively regulating AKT/PKB signaling pathway. The use of a non-canonical (CUG) upstream initiation site produces a longer isoform that initiates translation with a leucine, and is thought to be preferentially associated with the mitochondrial inner membrane. This longer isoform may help regulate energy metabolism in the mitochondria. A pseudogene of this gene is found on chromosome 9. Alternative splicing and the use of multiple translation start codons results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2015]

Classification according to ACMG Germline Pathogenicity v2019

Specifications for PTEN are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript:

Our verdict: Pathogenic. The variant received 15 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PS1Same amino acid change as known pathogenic		Same AA change, ≥2-star ClinVar pathogenic — very strong (PS1); ClinVar contains 1 P/LP entry with the same amino acid change (highest review level: 3 stars).
	PM1Mutational hot spot or critical domain		Missense neighbourhood hotspot (≥2 P/LP within ±8 AA, OR ≥ 5 vs. background) — PM1; In-domain: 0 pathogenic, 0 benign rare missense variants.; ±8 AA neighbourhood: 54 pathogenic, 0 benign (OR vs. background: 545.0).
	PM2Absent/extremely low in population databases		Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.000104 by highest known P/LP ClinVar AF 0.000104) — PM2 moderate.
	PM5Novel missense at known pathogenic residue		Different pathogenic missense at same AA residue in ClinVar (PM5); ClinVar contains a germline Pathogenic/Likely Pathogenic entry at the same amino acid position with a different amino acid change: p.R130L: Pathogenic/Likely_pathogenic (ClinVar VariationId 376509, 2 stars); Other variants at the same amino acid residue (not pathogenic): p.R130?: Uncertain_significance (ClinVar VariationId 2687576, 0 stars); p.R130?: Uncertain_significance (ClinVar VariationId 2687578, 0 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 1735874, 2 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 3903832, 2 stars); p.R130= (synonymous): Likely_benign (ClinVar VariationId 1648484, 1 star)
	PP2Missense in gene with low missense rate		Missense in gene constrained for missense variation where missense is common disease mechanism (PP2); Missense in a gene constrained for missense variation (gnomAD Z-score: 4.120). ClinVar shows strong pathogenic missense enrichment: 365 P/LP and 36 B/LB missense entries (ratio 10.1×).
